That's a bit of a pain. Would take ages to reload 192 games.
Been a while since I remember seeing an issue like this and for the life of me I can't recall what the issue was but these are the things I'd look at.
Maybe there's a game limit for WBFS volumes or with cIOS.
Try updating/downgrading cIOS.
Remove your loader's config files, maybe they have an issue that is causing loading problems.
Try a different loader, Wiiflow, configureable etc.
